Description

Technical Field

[0001] The utility model belongs to the technical field of hardware for building doors, windows and curtain walls, and relates to a small corner device with silent transmission and enhanced sealing. Background Art

[0002] Corner turners are common door and window hardware accessories, installed at the corners of the upper ends of door and window sash profiles. They are generally L-shaped, with horizontal and vertical connectors at either end. Inside, they are fitted with corner connecting strips that can slide horizontally and up and down, coordinating with other door and window hardware to achieve transmission functions and, in turn, open and close doors and windows. Existing small corner turners rely on aluminum rods to link the locking blocks, achieving transmission coordination between the locking point and the lock catch to seal the profile. However, gaps exist between the aluminum rods in the profile and between the small corner turners, resulting in loud transmission noise and window sealing deviations. Therefore, to address the above issues, a small corner turner with silent transmission and enhanced sealing is proposed. Utility Model Content
